摘要
The solubility properties of the zinc chloride- amino acids（Leu/Try/Val/Thr）- water systems at 25℃ in the whole concentration range have been investigated by equilibrium method, the corresponding phase diagrams and refractive index curves were constructed. The results indicate the formation of the congruently soluble compound of Zn（Leu）Cl2（ A） in Leu system and the incongruently soluble compounds of Zn（Try）Cl2· 1/2H2O（B）、 Zn（Val）Cl2· H2O（C）、 Zn（Val）2Cl2（D）、 Zn（Thr）Cl2· H2O（E） and Zn（Thr）2Cl2（F） in Try/Val/Thr systems, which have not been reported in literature. According to the phase equilibrium result, six solid complexes have been prepared in water, and their compositions have been determined by chemical analysis which are consistent with the results of phase diagrams.
